Comparing six evolutionary population synthesis models

, 2009
International audienceWe compare six evolutionary population synthesis (EPS) models, which have been popularly used in stellar populations analyses for galaxies.

The Effect of Different Methods for Accounting for α-enhancement on the Asteroseismic Modeling of Metal-poor Stars

The Astrophysical Journal
Constraining stellar models using asteroseismic and spectroscopic observations is a powerful method for precisely determining the fundamental properties of stars in different kinematic components of our Galaxy.

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions

FEBS Letters, EarlyView.
The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

Evolutionary population synthesis in stellar systems. I - A global approach [PDF]

, 1989
A new grid of 450 theoretical models for old simple stellar populations is presented. Evolutionary synthesis explores the influence of relevant parameters such as age, chemical composition, initial mass function, and stellar mass loss, on the integrated ...

On the Possibility of Chemically Driven Convection in Red Giants: Implications for the He-core Flash and Mixing above the Red Giant Branch Bump

The Astrophysical Journal
Turbulent mixing remains one of the primary uncertainties in the modeling of stellar interiors. In stellar evolution simulations, regions where mixing occurs are typically identified using instability criteria. A particularly interesting situation arises

Stellar evolutionary models: uncertainties and systematics

, 2005
In this last decade, our knowledge of evolutionary and structural properties of stars of different mass and chemical composition is significantly improved. This result has been achieved as a consequence of our improved capability in understanding and describing the physical behavior of stellar matter in the different thermal regimes characteristic of ...

Structure‐forward targeting of claudins with synthetic binders

FEBS Letters, EarlyView.
Claudins form the paracellular barriers between epithelial and endothelial tissues at tight junctions and are targets for molecular binders with the goal of modulating barrier permeability. Claudin‐binding molecules are relevant in drug delivery or in altering claudin interactions with disease‐causing proteins.

Evolutionary synthesis of simple stellar populations

, 1998
. We construct evolutionary synthesis models for simple stellar populations using the evolutionary tracks from the Padova group (1993, 1994), theoretical colour calibrations from Lejeune et al.

Grids of stellar models and frequencies with CLÉS + LOSC

, 2008
We present a grid of stellar models, obtained with the CLÉS evolutionary code, following the specification of ESTA-Task1, and the corresponding seismic properties, computed with the LOSC code. We provide a complete description of the corresponding files

Ages and zero age main sequence spin distribution of stars in detached eclipsing binaries

Astronomy & Astrophysics
Benchmarking fundamental stellar properties is essential for calibrating evolutionary models and establishing empirical relationships between mass, radius, luminosity, and related stellar properties.
